【题目】
News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.
Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That’s why many news anchors were worried: Will AI replace us in the near future?
To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.
Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person’s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them Into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs
Both the technologies used to make Xin’s performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don' t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.
【1】What does the underlined word "reluctant "in the first paragraph mean?
A. Delighted.B. Unwilling.C. Confused.D. Optimistic.
【2】What can we infer about previous news robots?
A. They read news without expressions.B. They looked like a human being
C. They could interview sports starsD. They could interact with audience.
【3】What do we know about the third technology?
A. This technology is very perfect so far
B. This technology is quite popular now
C. This technology remains at the theoretical stage
D. This technology is far from mature.
【4】From the last paragraph, we can draw a conclusion that____.
A. human news anchors should learn from AT anchors to save their jobs
B. Al anchors perform much better than human news anchors at present
C. Al news anchors won 't replace human news anchors in the near future
D. Xin Xiaomeng s expressions vary so naturally that they are true to life
【答案】
【1】B
【2】A
【3】D
【4】C
【解析】
本文是一篇说明文，上周日，新华社新闻主播辛晓萌成为世界上第一位女性人工智能新闻主播，本文介绍了人工智能背后的技术，并指出在不久的将来，人工智能新闻主播不会取代人类新闻主播。
【1】词义猜测题。根据画线词后的“Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday”及第二段中的“That’s why many news anchors were worried: Will AI replace us in the near future?”可知，担心将来自己的工作会被人工智能取代的新闻主播一定不愿意透露下面这个消息：上周日，新华社新闻主播辛晓萌成为世界上第一位女性人工智能新闻主播，由此可知画线词词义为“不愿意的”，故B项正确。
【2】推理判断题。根据第二段中的“Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading.”可知，与以前的机器人主播不同的是，辛晓萌读起来不像一台冷冰冰的机器，就像是一个活生生的人，她读新闻的时候脸上的肌肉能够伸展和放松，面部反应也发生了变化，由此可知，以前的机器人主播读新闻时面无表情，故A项正确。
【3】推理判断题。根据最后一段中的“The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don' t always change according to the content. As a result, her expressions look anything but human.”可知，真正的难点在于第三技术，使辛晓萌的面部表情根据新闻报道的内容而变化，事实上，辛晓萌的表情不总是随着内容而变化，她的表情一点也不像人类，由此可知，第三技术还远远不够成熟，故D项正确。
【4】推理判断题。根据最后一段中的“Actually. AI is still no match for human qualities.”可知，人工智能仍无法与人类素质相匹敌，由此可知，在不久的将来，人工智能新闻主播不会取代人类新闻主播，故C项正确。
词义猜测题的难度较大，理解画线词的上下文是关键，例如本篇第1题，根据画线词后的“Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday”，再结合第二段中的“That’s why many news anchors were worried: Will AI replace us in the near future?”可知，人类新闻主播担心将来自己的工作会被人工智能取代，所以他们一定不愿意透露上周日，新华社新闻主播辛晓萌成为世界上第一位女性人工智能新闻主播这个消息，由此可知画线词词义为“不愿意的”。

It seems that if the result is bad, which people work for will be meaningless. Personally speak, the process of fighting for the goal is less important than the result. When we fight for our goals, we will be devoted what we are doing and try to improve us. If we fail in the end, when we look back on the beginning, we will find that we are no longer the childish one. We have grown up. What's the more, in the process of fighting, we got close to success, as the saying goes that failure are the mother of success. So don't treat the result so serious; just enjoy the process.

【题目】Directions: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.
The Internet E-commerce and globalization are making a new economic age possible. In the future, capitalist markets will largely be replaced by a new kind of economic system based on 【1】 relationships, contractual arrangements and access rights.
Has the quality of our lives at work, at home and in our communities increased in direct proportion to all the new Internet and business-to-business Internet services being introduced into our lives? I have asked this question of hundreds of CEOs and corporate executives in Europe and the United States. Surprisingly, virtually everyone has said, “No, quiet 【2】.” They say they are working longer hours, feel more stressed, are more impatient, and are even less civil in their dealings with colleagues and friends-not to mention strangers. And what’s more revealing, they place much of the blame on the very same technologies they are so 【3】 supporting.
The technological leader promised us that access would make life more convenient. Instead, the very technological wonders that were supposed to 【4】 us have begun to enslave us in a web of connections from which there seems to be no easy 【5】.
If an earlier generation was preoccupied with the quest to enclose a vast 【6】 land, the .com generation, it seems, is more caught up in the colonization of time. Every spare moment of our time is being filled with some form of commercial connection, making time itself the 【7】 of all resources.
And while we have created every kind of labor-and time-saving device to service our needs, we are beginning to feel like we have less time available to us than any other humans in history. Maybe we need to ask what kinds of connections really 【8】 in the e-economy age. If this new technology 【9】 is only about super efficiency, then we risk losing something even precious than time-our sense of what it means to be a(n) 【10】 human being.

The summer holiday is coming. My classmates and I are talking about how to do during the holiday. We can chose between staying at home and take a trip. If we stay at home, it is comfortable but there is no need to spend money. But in that case, we will learn little about world. If we go on a trip abroad, we can broaden your view and gain knowledges we cannot get from books. Some classmates suggest we can go to places of interest nearby. I thought that it is a good idea. It does not cost many, yet we can still learn a lot.
